Well, I've been working on building a 4th mech with a more unique color pattern. I really don't want to use accent colors unless I can get a couple more mechs so I can have seperate groups with colors. But I have been playing around with the handheld weapons...

Anti-material rifle at the top, from left to right, commander's battle rifle, machine pistol, carbine, & standard batttle rifle... Hmm... looking at this right now I have an idea for the carbine so might redo that one.
